Since launching the GPWM which originally started with the six thematic areas (1: Waste and Climate Change; 2: Waste Agricultural Biomass; 3: Integrated Solid Waste Management; 4: E-waste Management; 5: Marine Litter; and 6: Waste Minimization), two more thematic areas (6: Hazardous Waste Management; and 6: Metal Recycling) were introduced to the GPWM.

The GPWM website will be upgraded to the kNOwWaste Platform of UNEP International Environmental Technology Centre (IETC). The IETC "KNOwWaste" Platform supports the exchange of information, knowledge, practices and experiences among countries, regions and cities, empowering their capacity to manage waste related matters. On the "kNOwWaste" it will be possible to consult experts and other users that might be facing similar issues or that have may have a solution to propose.

 International agencies, Governments, businesses, academia, local authorities, and nongovernmental organizations. They can have an opportunity to enhance international cooperation, outreach, advocacy, knowledge management and sharing, to identify and fill information gaps in waste management, to protect human health and the environment and to tackle adverse impacts of unsound management of waste. And they also are able to raise awareness, encourage political will, and increase capacity in order to promote resource conservation and resource efficiency through waste prevention and to recover valuable material and/or energy from waste.
